Question

Can you help me with this? Someone deleted one of my originals.

Answer 1

Vertically opposite angles are equal

So, 11x + 33 will equal 15x+5

11x + 33 = 15x + 5

-11x both sides

33 = 4x + 5

- 5 both sides

28 = 4x

÷4

7 = x

Check:

11 x7 = 77 + 33 is 110

15 x 7 = 105 +5 = 110

Ans: x = 7

Hope this helps!
